VEHICLE-WHEEL.

Specification of Letters Patent.

Application filed June 15, 1914. Serial No. 845,288.

. a citizen of the United States of America,

vpreferably formed of pressed steel, and hav' .ing the cylindrical portion D which constiresiding at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vehicle-lVheels, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle wheels designed for use as drivers in motor vehicles, and has more particular reference to the construction of the wheel hub and brake-drum.

In the present state of the art it is usual to form the-brake-drum as an attachment to the wheel, being provided with means for se-- tutes the bra-ke drum, the web portion D which lies adjacent to the spokes of the wheel, and the cylindrical portion D projecting oppositely from said Web and constituting the hub.

The portion D forms a recess for receiving the anti-friction roller bearing E, and

an inwardly-turned flange D forms a thrust shoulder for oneend of this bearing. The opposite end of the bearing is secured by a circular plate F which lies adjacent to the web D and is secured thereto byclamping bolts G, which also secure in. place the spokes H, an annular outer clamping flange I and the drive-head J which is connected to the drive axle B. This drive-head J is preferably of the dished form shown, so as to provide clearance for the end of the axle housing A and 'nut K for clamping the bearing E against an opposed shoulder on the housing A. 4

With the construction as described, the brake-drum and hub being die-fashioned are always in true concentric relation, and the apertures for the bolts G are also exactly positioned. This avoids the necessity of any machining operation, thereby cheapening the cost of manufacture while the assembling of the parts is also facilitated.

Vhat I claim as my invention is In adevice of the character described, the combination with an axle, a drive shaft therein and ahead at theouter end of said drive shaft for communicating the torque to the wheel, of a pressed -metalmember having a brake-drum, an inwardly-extending web and a cylindrical portion projecting oppositely from said web, constituting a hub; an anti-friction bearing seated in said hub upon said axle, a flange for clamping said bearing in said hub, spokes extending radially from said hub, a flange on the outer face of said spokes, and a clamping bolt for securing said bearing clamping flange,

spoke-clamping flange and torque head to I each other.
